No, that's where TLS keys go. Not DKIM keys.
Dear All,
Until now when I sent an email with a new email address that email address was registed in the "Contacts" folder.
It is not happening anymore. I suppose that is happening since last Centos 9 update (with glibc (??) update, one of the Citadel dependencies was updated).
Notice that Thunderbird had also a recent update.
Is it happening with someone else?
Thank you,
Luís Gonçalves.
I made a dump and a load of the database and it start working but I do not have certain about if it is the reason.
Now a question. The contacts not being updated with new email addresses, is it meaning that the emails were not sent?
For information, the emails appeared in the "Sent Itens".

After installing Citadel no DKIM was generated.
Is there a way for me to install a public and private DKIM key in Citadel sever
After installing Citadel no DKIM was generated.
Is there a way for me to install a public and private DKIM key in Citadel sever
Again, there is no way to install a user-generated DKIM key into Citadel. Citadel generates the private key for each domain and stores it in the database. When it does so, the corresponding public key is posted to the "Aide" room.
If you are missing your key, you can delete and re-create your local domains on this screen:
[ Administration --> Domain Names and Internet Mail Configuration --> Local host aliases ]
When you do so, new DKIM keys will be generated and posted, and you can use those.
Ok, so I just ran a quick test and confirmed: you can add a bogus domain (example.xxx or whatever) and then go right ahead and delete it, and it'll post the keys for all of your existing domains as well.
I have deleted the domain and a new DKIM record was generated but using easydmarc to test it gives the following result:-
We couldn't find a DKIM record associated with your domain. You need to generate DKIM record to protect your domain against email phishing attacks.
easydmarc appears to be a scam site that wants to sell you a service, and deliberately shits on your domain to make you buy it.
Instead, try https://dkimvalidator.com
No signup. It gives you an address to which you send an email. You send that address an email, then go back to the site and it tells you if that message was properly DKIM signed.
Many thanks can now send emails to google accounts without rejection
Thanks again
(I hope this is the Citadel Support room)
Hello,
I'm trying to install Citadel on my Rpi3 using your easyinstall script. The script does not complete. During installation it needs a certain Berkeley database file. This download is extremely slow and/or the file cannot be downloaded. When I go to https://easyinstall.citadel.org/db-18.1.40.tar.gz myself using a browser the download also fails.
Any help is appreciated.
Regards Bart
A piece of the script output is:

I don't want to speak for LG as i'm not sure if hes hosting the files via the same network provider as the board, but there have been network issues here of late here on the board, and if my guess is right, it could/would effect that too.
Keep retrying..
Sorry, IG not LG.. fat fingers.
Also, i was able to download it a bit ago, yes slowly, but it did finally complete. Id offer to share it out on google or something, but if you are smart, you would not trust me anyway.

Subject: Re: Berkeley DB cannot be downloaded
That's correct, actually. Over the last couple of days we've had some pretty bad network flooding. I think I've got most of it worked out so try again.
First of all I am very new to this, so my apologies in advance.
I've had a longtime project to setup an email server that I'm getting back to. I was following an older video as guidance in which Citadel had an Administration tab right next to the Advanced tab. I already have the domain and need to enter that information so that I can create the various email accounts using the Citadel Server. Without the Advanced tab, I can't find where to enter the domain information. With so much reference information I can't seem to find what I need, I have no doubt that it's there-somewhere. Can someone point me in the right direction?
Subject: Reproducible SIGSEGV caused by concurrency between IMAP FETCH, SMTP DATA, SMTP forwarding (Sieve), and SMTP queue delivery
Hello Citadel Team,
I'm reporting a reproducible segmentation fault (SIGSEGV) observed in production, which appears to be caused by a concurrency / thread-safety issue in Citadel under normal usage conditions. I have collected multiple core dumps showing consistent call patterns and triggers.
Deployment: Docker
OS: Linux x86_64 (glibc-based)
Protocols in use:
* IMAPS
* SMTP (inbound + outbound)
* SMTP queue delivery
Sieve: Enabled (email forwarding rules)
No custom patches. No abnormal traffic patterns.
Observed Behaviour
Citadel crashes with SIGSEGV during normal operation. The crashes began after ~26 weeks of stable, uninterrupted operation, without any infrastructure or configuration changes. The only relevant behavioural change before the first crash was the introduction of new Sieve forwarding rules, which increased outbound SMTP activity.
From Core Dumps
The crashes consistently occur when the following operations overlap in time:
Thread A – IMAP FETCH (user reading mail)
imap_fetch_body()
imap_do_fetch_msg()
imap_do_fetch()
imap_command_loop()
Thread B – SMTP DATA (receiving mail)
smtp_data()
smtp_command_loop()
CtdlReadMessageBodyBuf()
StrBufTCP_read_buffered_line_fast()
Thread C – SMTP Forwarding / Queue Delivery
smtp_attempt_delivery()
smtp_do_queue()
smtp_do_queue_full()
curl_easy_perform()
curl_multi_poll()
Additional Concurrent Activity
* TLS handshakes (CtdlStartTLS, imaps_greeting, pop3s_greeting)
* Session cleanup and hooks (PerformSessionHooks, do_housekeeping)
* In some crashes, XMPP hooks are also active
Analysis / Suspected Root Cause
Based on repeated core dump analysis:
-
These execution paths share internal buffers/message structures
-
Some of these paths appear not to be fully thread-safe
-
Increased outbound SMTP concurrency (introduced by Sieve forwarding) significantly raises the likelihood of these paths overlapping
-
This results in memory corruption, eventually causing a SIGSEGV (often observed shortly after read(), select(), or buffer handling)
Important notes:
-
The Sieve rules themselves are valid and correctly defined
-
The issue is not caused by user error or misconfiguration
-
Forwarding acts as a trigger, not the root defect
Reproduction Pattern (High-Level)
While not 100% deterministic, the crash frequency increases significantly when:
-
Sieve forwarding is enabled for active mailboxes
-
Inbound SMTP traffic is present
-
Users fetch messages (IMAP FETCH) concurrently
-
SMTP queue delivery runs in parallel (especially to external domains)
Reducing worker thread concurrency significantly reduces or eliminates crashes, which further suggests a concurrency-related issue.
Expected Behaviour
Citadel should be able to safely handle concurrent:
-
IMAP FETCH
-
SMTP DATA
-
SMTP forwarding (Sieve)
-
SMTP queue delivery
without memory corruption or segmentation faults.
Questions for the Development Team
-
Is this a known concurrency issue?
-
Has this behaviour been addressed in newer Citadel versions?
-
Are there recommended patches, configuration flags, or build options to mitigate this safely?
-
Would additional debugging data (full core dumps, symbols, logs) be helpful?
Thank you for your time and for maintaining Citadel.
